Influence of processing parameters on flexural properties of injection moulded polypropylene was investigated using response surface approach. Investigations were focused on the rheological behaviour of injection moulded polyvinyl chloride (PVC) products at different temperature. Flexural strength test was conducted on the test specimens moulded at different injection parameters ranging from 1700C to 2100C barrel temperature, 33 seconds to 43 seconds cooling time, 46 rpm to 56 rpm screw speed and 350C to 450C mould temperature. The test information was subjected to design expert 10.1 analyses. The results obtained indicate that a melt temperature has an effect on viscosity of injection moulded polyvinyl chloride. Also, optimum parameter values of 390C mould temperature, 52 rpm screw speed, 1900C barrel temperature, cooling time and flexural strength respectively were obtained. The results of this finding will be useful in polymer industries were polyvinyl chloride is been used as a raw material during injection moulding were flexural strength is a paramount requirement of the output component.
